You cannot completely hide your IP address, and there should be no reason for even attempting to do it.
There are a few illegal activities that might require you to use an alternative IP address, but you can still be traced if the illegal activity requires the authorities to locate you so that you can be prosecuted.

Look up free VPN's, they encrypt everything you do on the internet, (I do not accept responsibility if things don't work)
?
go to youtube and search for "hide ip"
you'll see a lot of choices you could try out
